The AZPG-22-045RQC12MB SO696 gear pump belongs to the High Performance AZPG Gear Pumps series and is produced by Bosch Rexroth. Designed for hydraulic automation circuits, it converts mechanical input into a controlled oil flow. A geometric displacement of 45 cm³ per revolution defines the volume delivered on each cycle. The unit runs with clockwise shaft rotation to match common prime movers. Minimum operating speed is 500 rpm when pressure is below 100 bar and viscosity is 12 mm²/s, while maximum speed reaches 2600 rpm at the p2 rating, providing a wide flow range. A transmissible torque limit of 180 Nm specifies the mechanical load the drive train can impose. The shaft diameter is 25.4 mm, and the SAE J744 22-1 shaft end profile ensures interchangeability with standardized couplings. Torque is carried through a 6.35 mm key that prevents rotational slip between the shaft and the driven element.
Mounting is achieved with an SAE J744 101-2 (B) flange so the pump bolts directly to compatible power units. It operates with HLP hydraulic oil according to DIN 51524 to maintain lubrication and wear resistance. Continuous pressure capability is 250 bar, intermittent service allows 280 bar, and transient peaks up to 300 bar are accepted without damage. For size 45 shafts the p2 limit of 225 bar protects against excessive radial loading. Fluid retention depends on an NBR seal, and the shaft seal measures 42 × 26 × 7 mm to keep contaminants out. These pressure ratings, sealing elements, and the specified flange interface enable the pump to deliver reliable flow in heavy-duty industrial power units that demand stable performance under elevated system pressures.
